Hi Mazza27
Hope you're feeling better today. Sounds like you are peri-menopausal. It is very difficult to know what's causing what at this point because your hormones will be fluctuating considerably.
If you suffer with heavy bleeding then why not ask for another coil (do you mean the Mirena coil?) if you felt well on this, and then if you need to you can add oestrogen to deal with menopausal symptoms such as flushes and sweats, and hopefully others too?
